IrDA (Infrared Data Association)
The Infrared Data Association (IrDA) was formed in 1993 by about 50 companies including HP, IBM, Sharp, and Sony. IrDA defines point-to-point infrared wireless transfer.
Wrong Mode or transfer rate causes decode failures. For channel-prefix differences, see Settings.
